The investigation into the circumferential mechanical properties of tubular materials has been receiving increasing attention, since the tube hydroforming process has been used in the tubular materials forming field, because the circumferential mechanical properties have a significant effect on the hydroformability of the tubular materials. In the present study, a method for evaluation of the circumferential mechanical properties of the tubular materials with the flaring test was proposed. The expressions for the yield stress, strain hardening coefficient and exponent values of the tube were successfully derived based on the geometrical and mechanical relationships in the tube flaring test. To verify the reliability of this method, the calculated results of the yield stress, strain hardening coefficient and exponent values, obtained from the newly proposed method, were compared to the ones obtained with the conventional tensile tests. It was found that the method proposed in the current study is reliable, with high accuracy. The method is appropriate to evaluate the circumferential mechanical properties of the tubular materials.

“…The results indicated that the homogeneity of the thickness distribution improved as compared to the condition of quasi-static, and the improvement was examined numerically. Quaisie et al [6] investigated the water-jet shock microforming process utilizing a variety of incidence pressures. The testing results showed that under this dynamic microforming approach, the surface morphology of the metallic foils achieved good geometrical features and that there were no cracks or fractures.…”

This paper presents a comparative study using a newly technology called water jets cavitation to fabricate micro feature on 304 stainless steel foils with a thickness of 100 µm and surface enhancement of 8090AlLi alloy sample with a thickness of 4 mm, where angular nozzle and a designed cavitation system were used with an incident pressure of 8-20 MPa. The bulged sample and the effect of incident pressure on the cavitation zone range were investigated. The experimental results indicated that the formed sample bulging depth of the outer ring shock zone and the bulging depth of the jet shock zone were not ideal, while the pits in the cavitation shock zone (that is, pits 2~4 and 10~12) obtained good geometric characteristics. Finally, the consistency of the maximum bulging depth was relatively good. The micro-bulged parts showed that the micro-pits in the cavitation shock zone had a large bulging depth and their uniformity was relatively good, indicating that the circular array feature micro-die has good performance in the cavitation water jet shock micro-bulging process. The effect of incident pressure on the range of cavitation zone, also indicated that the effective area of action of the cavitation water jet showed a ring. That is when the incident pressure was 20 MPa with a target distance of 120 mm, the maximum cavitation shock (bulging) zone showed rings of 3.5 ～21.1 mm with the 304 stainless steel foil and 3.5 mm~21.4 mm also with the 8090Al-Li alloy plate which were approximately same.

“…Using experimental and simulation results, they have concluded that loading paths based on the finite element method can significantly reduce trial and error and increase productivity, as well as extend the hydroforming process capability in the formation of complex parts [4]. Zhang provides a brief overview of recent developments in hydroforming processes, including process changes used to form tubular and flat components, hydraulic test apparatus for parts, and how and how process pressure is applied, their specifications and applications, especially its applications in automotive processes [5]. Mahang and Tsai have developed a pipe hydroforming process using a new movable mold design to reduce internal pressure and maximize the thinning ratio in the product [6].…”

In this paper, using the Sobol sensitivity analysis method, which is based on variance, 11 factors affecting the optimization of the loading path of the hydroforming process are investigated, then the feasibility and validation of the results with other optimization methods such as finite element and experimental method are reported. Is Input factors include, expansion pressure, final pressure, yield time, end of expansion time, intermediate mandrel displacement, final mandrel displacement, intermediate mandrel displacement time, initial position of reciprocating mandrel, final position of reciprocating mandrel, start time of reciprocating mandrel and time The stops of the reciprocating mandrels are considered, then the effect of each of them on the minimum thickness and maximum height in the loading path of the hydroforming process to produce T-joints is investigated and reported in detail. Quantitatively and qualitatively, the optimal values are obtained for each of the 11 input factors and are calculated based on the loading paths.
